Welcome to the GHC Developer Wiki

This is the home for GHC developers, one place for all the resources related to developing GHC. If you're only interested in using GHC, then you probably want ​The GHC home page instead.

Please help us improve the information here. You can easily do this by editing the wiki directly. Just
log in as user guest with password guest. The "Help/Guide" link at the top of every page gives a good description of the markup language etc.

Notices

We ran a GHC Hackathon just before ICFP 2006 in Portland, Oregon. As a result, The GHC Commentary is now completely revised, and it's in the GHC Wiki, so you can help keep it up to date. (For the dedicated, videos of the Simons presenting this material are on the Hackathon page.)

Internships at Microsoft Research, Cambridge, working on Haskell and GHC

GHC developers also hang out on #ghc channel on ​FreeNode. This is a good place to ask questions related to working on GHC itself; if you have more general questions then #haskell is probably more appropriate.

The (new) GHC Commentary
Documentation on the design, architecture, and implementation of GHC itself,
with references to the actual source code. (Don't confuse this with the ​old commentary. This one is new and up to date.)
